Nonvolatile semiconductor memory device
Abstract:
A nonvolatile semiconductor memory device includes: a memory element in which a rate of charge discharge between two electrodes of the memory element differs according to a logical value of stored information; cell wiring connected to one electrode of the memory element; a sense amplifier having a sense node connected to the cell wiring, the sense amplifier reading the logical value of the information by comparing a potential of the sense node with a reference potential; and a readout control circuit capable of switching between a dynamic sense operation performing readout by precharging the cell wiring and discharging or charging the cell wiring via the memory element and a static sense operation performing readout in a state of a current load being connected to the sense node.
